Those are good reasons for separating the domains.

Your policy is more comprehensive than mine.

How does that chromium_renderer_t work?  Is that a standard chrome feature or 
something special you did?  It would probably be best to have a comment in the 
policy about this.

It seems that the only difference between chromium_xdg_config_t and 
chromium_xdg_cache_t is that the latter can't be read by chromium_renderer_t.  
Is that sufficient reason to have an extra type?

Apart from that it appears ok to me.  NB I haven't run it, I've just inspected 
it.
